The interactive board according to the present invention includes a projector hanger 2 for supporting the projector 1, a position detection sensor 3 for detecting the position of an input means such as a marker or a stylus on the board, and a personal computer stand 4. It is characterized by this.

  The present invention is applicable to both the wall surface fixed type and the movable type boards. The first embodiment shown in FIG. 1 and FIG. 2 is for an existing large-sized flat blackboard with a fixed wall surface, and the projector hanger 2 is movable along the board 5 in the lateral direction. Although the position detection sensor 3 in this embodiment is installed integrally with the projector hanger 2, it can also be installed separately like 2nd Embodiment mentioned later (refer FIG. 3).

  In the example shown in FIG. 1, one slide rail 6, 7 is laid along the upper side and the lower side of the board 5 fixed to the wall surface, and a slider that can slide or roll on each slide rail 6, 7. 8, 9 are installed. In order to further improve the convenience in use, a plurality of slide rails 6 and 7 (two in the figure) may be laid as shown in the example shown in FIG. FIG. 2 shows an example in which a hook type hanging tool 32 is attached to the lower stage of the lower slide rail 7 and the wiring cord 33 is hung there.

  The configurations of the slide rails 6 and 7 and the sliders 8 and 9 engaged with the slide rails 6 and 7 are arbitrary. For example, the slide rails 6 and 7 have a C-shaped cross section, and the sliders 8 and 9 are the slide rails 6 and 7. It can be set as the block provided with the rollers 8a and 9a which are locked inside and roll (refer FIG. 5). Alternatively, an LM guide may be used as the slide rails 6 and 7, and a block having an LM ball may be used as the sliders 8 and 9.

  FIG. 6 shows an example of a cross-sectional shape of the slide rails 6 and 7 when a plurality of slide rails 6 and 7 are run side by side. In the example shown in FIG. In the example shown in (B), the front-facing rails are provided separated by two steps, and in the example shown in (C), the upper stage is an upward rail and the lower stage is a front-facing rail. In the example shown in D), the upper stage is a front-facing rail and the lower stage is a down-facing rail, and various other combinations are possible depending on the application. Although not shown, a vertical rail can be arranged on the side of the board 5 in addition to the slide rails 6 and 7 if necessary.

  In the first embodiment, the sliders 8 and 9 are connected by the connecting support column 10, and the slider 8 and the slider 9 move together along the slide rails 6 and 7. For example, the position detection sensor 3 is integrated with the projector hanger 2 by being fixed to the connection column 10 and can be moved together with the projector hanger 2.

  The projector hanger 2 has an arm 11 for supporting an image projection surface of a board 5 having functions of various boards such as an electronic blackboard, a white board, and a screen board. Installed. The arm 11 is supported so that, for example, the projector 1 can move in the vertical direction and / or the length direction of the arm 11 so that the projector 1 moves to a position suitable for projection and faces a suitable direction. At the same time, it is supported so that it can pivot in the horizontal direction and / or the vertical direction.

Preferably, the arm 11 is installed on the slider 8 so as to be able to turn with respect to the board 5. For this purpose, for example, by embedding a pipe-shaped shaft supporting cylinder 1 6 to the slider 8, it may be the arm 11 to pivotally inserted into the shaft supporting cylinder 1 in 6. In that case, it is preferable to provide means for fixing the arm 11 at a desired turning position and height position.

Stop As the means, the upper end portion of the shaft supporting cylinder 1 6, configured to dispose the tightening possible tightening band 13 surrounds the arm 11 (see FIG. 7 (A)), from the outside of the shaft supporting cylinder 1 6 A configuration in which a screw is screwed in and the arm 11 is pressed at its tip to stop its movement, a pin 41 with a spring is inserted from the outside, and the tip of the pin is appropriately drilled in the arm 11 by the action of the spring. A configuration for entering and locking (FIG. 7B) and other arbitrary locking means can be employed. Alternatively, without providing these locking means, for example, the clearance between the outer peripheral surface of the arm 11 and the inner peripheral surface of the shaft support cylinder 16 is about 0.6 mm, and the insertion depth of the arm 11 is 250 mm or more. By ensuring, it is possible to adopt a method of giving sufficient sliding resistance between both peripheral surfaces.

  With this configuration, the arm 11 is pivotally supported by the slider 8 and can move up and down in a state where the tightening means is loosened, and the projector 1 attached to the tip of the arm 11 can be moved to an arbitrary height and direction. It becomes possible to arrange in. Normally, the arm 11 is swung and moved up and down manually, but may be mechanically driven by a cylinder or a motor.

  The projector 1 is attached to the tip of the arm 11 directly or via the projector suspension 21. For example, the projector suspension 21 includes a cylindrical slide frame 22 installed on the arm 11 by causing the arm 11 to enter, a slide support cylinder 23 attached to the slide frame 22 in the vertical direction, and a slide. A suspension shaft 24 that is slidably inserted into the dynamic support cylinder 23, a slide rod 25 that is attached to the lower end of the suspension shaft 24 and slides in a direction orthogonal to the suspension shaft 24, and is suspended by the slide rod 25. And a projector fixing plate 26 (see FIG. 8).

  In this case, the arm 11 can slide in the slide frame 22, in other words, the slide frame 22 can move along the arm 11. The movement of the slide frame 22 can be performed by loosening the fixing screw 27, and the sliding of the suspension shaft 24 can be performed by loosening the fixing screw 28 screwed into the sliding support cylinder 23. it can. The slide bar 25 is attached to the lower end portion of the suspension shaft 24 via a flexible clamp 29. The flexible clamp 29 is a metal fitting that can connect two axes at a desired angle, and the slide bar 25 can be in a horizontal state or an arbitrary inclined state with respect to the vertical suspension shaft 24. .

  FIG. 9 shows another method of attaching the projector suspension 21 to the arm 11. That is, a shaft insertion portion 36 for inserting the suspension shaft 24 of the projector suspension 21 is provided on one surface of the substrate 35, and the tip of the arm 11 is orthogonal to the suspension shaft 24 on the other surface. An arm attachment 34 provided with a U-shaped bender bolt 37 inserted and received in the direction is used. A tightening screw 38 is screwed to the shaft insertion portion 36, and the U-shaped bender bolt 37 passing through the substrate 34 is also attached. A tightening nut 39 is screwed to one end.

  In this case, by loosening the tightening screw 38 of the shaft insertion portion 36, the suspension shaft 24 inserted through the shaft insertion portion 36 can be moved up and down, and the tightening nut 39 of the U-type bender bolt 37 can be moved. By loosening, the tip end of the arm 11 inserted therethrough can be slid, and the horizontal position and height position of the projector 1 can be adjusted by each operation.

  With the above configuration, the projector 1 can move in the length direction of the arm 11 and can move in the vertical direction. Further, since the projector 1 is connected to the slide bar 25 via the projector fixing plate 26, the tilt angle of the projector 1 can be arbitrarily set by loosening the tightening screw of the flexible clamp 29 and changing the tilt angle of the slide bar 25. Therefore, in combination with the turning of the arm 11, the operation of arranging the projector 1 at the optimal position and angle for projection can be performed easily and quickly.

  In addition to the above, the projector suspension 21 has a configuration in which the suspension shaft 24 and the slide rod 25 are connected via a universal shaft joint, or the slide rod 25 is omitted, and the suspension shaft 24 is omitted. Further, a configuration in which the projector 1 (or the projector fixing plate 26) is directly connected via a universal shaft joint is also conceivable. In the case of the configuration using this universal shaft joint, the freedom of the swing motion of the projector 1 is further increased.
